Join MP4 files with Front End Digital Media Workshop

Want an easy way to join MP4 clips together? Front End Media Workshop, a nifty piece of Mac software published by the now defunct K-werkx, can definitely help you out. While the folks that put it together aren’t online any longer, the app is still available for download from CNET.

The app (it shows up as FE_DigitalMediaWorkshop in the Apps folder by the way) is meant to do a bunch of other things, but I found it most useful to join together several MP4 clips from my video collection.

For example, I’d purchased a DVD of “The Curious Adventures of Mr. Wonderbird“, a re-titled version of the 1952 original, La Bergère et Le Ramoneur. The film is little known, and features the dramatic escape of a pair of lovers from the claws of a despotic ruler. A curious bird helps them escape and orchestrates the toppling of the ruler’s oppressive regime, which mirrored, at the time, what was going on behind the iron curtain of Eastern Europe. Peter Ustinov voices the bird and also narrates the story.

At any rate, I’d copied the DVD to my computer only to later realize that I’d done it by chapters instead of copying the entire movie as a single file. Front End Digital Media Workshop allowed me to drag the five or six clips for each chapter onto its main window, drag and drop to arrange them in order, then, within minutes, join them together as a single file. The output was saved to the desktop in a folder (one for each join operation), where I could review, rename and archive it.

Sure, if you have Quicktime Pro, you can join video files there, or you can also import them into iMovie, but a small, single purpose app that does it faster and without a lot of fuss scores higher in my book. I may even use it later to snip clips from the beginning and end of some of my other video files, since I see that it has that feature built in as well.

First snowfall of 2008

As I drove home from work yesterday, a light snowfall started coming down. I took out my mobile phone and recorded this video clip. I was at the Georgetown Rd exit off I-495, in Bethesda, MD.

If I am to be accurate, I should say it’s not the first snowfall of the season, but the second. It is, however, the first I managed to capture on video. We had another brief snowfall earlier in the week, which, much like this one, melted upon contact and didn’t even wet the ground.

I see that others are getting much more snow [via], but given what they have to go through, I’ll take my little snowfall over this dangerous winter morning any day:

Camera preview: Canon EOS 5D Mark II DSLR

I’m a little late to the table with my thoughts on the new 5D, but I have an excuse: I’ve been traveling abroad (see this, this and this) and only now managed to sit down and think about it. There’s also an advantage to this: I got to read through the other reviews that have come out before I wrote mine.

So, what sources did I consult?

  • The Canon website was the first place I looked. There’s the official press release for the new 5D, and then the 5D Mark II pages. (I looked at the press release back on September 20th, when it came out.) Canon has also published 1080p HD video clips shot with the new 5D on their website, and they’re definitely worth checking out. They make a point to specify that the clips were shot with a pre-production 5D Mark II, so they may not accurately represent the quality of the production camera.
  • Digital Photography Review put together a very detailed review of the new 5D, as usual. Their review was very helpful to me.
  • The Online Photographer talked about the quality of the 5D’s HD video, and he brought up a good point. I’ll mention it here because I felt the same way when I saw Vincent LaForet’s video: it just wasn’t very good in terms of realization. It didn’t tie together, it felt empty… In a way, this was to be expected when there were only two days to write it, produce it, film it and edit it. But the quality of the video from the 5D Mark II was definitely worth seeing.
  • Robert Reichmann from the The Luminous Landscape posted pre-production video shot with the new 5D and gave his first impressions of the camera. He was in a hurry as well, as he was leaving for a trip to Africa and had only 48 hours with the camera. He says that the video is very high quality (so high that MBPs playing the full resolution video will skip frames), and there is no jellocam effect, where you see balooning artifacts due to slow recording of the data by the CMOS.
  • PopPhoto chimed in with a quick preview that did a little feature comparison between the old and new 5Ds.
  • On Taking Pictures had an interesting first reaction. He pointed out that the AF system should have been improved. It’s still the same 9-point AF found on the original 5D, and it has its limitations, as I can attest.
  • Thomas Hawk wrote up his impressions. He’s excited and plans to get one as soon as they’re available.
  • I found out about a new review aggregation site while I was writing this post. It’s called TestFreaks, and it’s one of the places where I looked for other reviews of the 5D. So far, they’ve posted links to four reviews for this camera, out of which an Italian review was worthwhile, particularly their side-by-side comparison of the old and new 5Ds. The rest of the linked reviews simply spewed the press release, which involves no effort or thought whatsoever. But I think the site is useful as a place to check for reviews when you want to learn more about a product.

What about me? Well, I wrote about the original and new 5D back in August 2007, when I took a shot a predicting the features of its new iteration. And I also wrote another article a little over a month ago, on August 28, where I talked about the coming convergence of DSLRs and video, and predicted that after the launch of Nikon D90’s 720p HD video capabilities, 1080p HD video wouldn’t be far off. Amazingly, Canon had already been at work on that very same feature, and launched it with the new 5D shortly afterward.

Let me first indulge myself and see how right (or wrong) I was in my own predictions about the 5D Mark II:

  • EOS integrated cleaning system (YES)
  • Live View (YES)
  • 16 Megapixels (NO, even better)
  • Up to 3200 ISO (NO, even better)
  • Increased battery life (YES)
  • Weatherproofing (YES)
  • AF upgrade (NO, unfortunately)
  • Increased zones for exposure metering (YES)
  • Shutter durability up to 300,000 cycles (NO, but still increased to 150,000 cycles)
  • 3″ LCD (YES)
  • Retail price $3,300 (NO, it’s $600 lower)

What I did as I read through the official specs found on Canon’s website and through the other reviews was to take notes of the interesting differences between the original 5D and the new 5D.

How could the new 5D be even better?

  • AF should have been upgraded to something faster and more accurate
  • RAW files still CR2 format; it would have been nice to standardize on the DNG format
  • Color space options are still only sRGB or AdobeRGB; what about ProPhotoRGB?
  • HDMI Out miniport puts out great video but NO audio, which is unfortunate
  • Hand grip now slightly thicker, but space between grip and lens barrel slightly smaller, which means you may end up jamming your fingernails into the lens as you hold the camera, should you have thicker fingers. This was a point of contention with the 30D, was addressed in the 40D, and now I see it potentially coming back (though to a lesser degree) in the 5D Mark II.
  • No controls for video other than focus and exposure compensation once you start recording. It really does seem like the video mode was grafted onto the camera, as Luminous Landscape puts it in their review. Plus, the microphone input socket isn’t a pro-level socket, but a plastic one that can easily break if you’re not careful.
  • Recording video will drain the battery a LOT faster than shooting photos. And it will take up space. You’ll go through a single 4GB CF card in about 11-12 minutes if you’re shooting video. I guess this is to be expected given that the camera records full HD video on a huge 35mm sensor.

On the plus side, it’s interesting to note that I paid $100 more for my original 5D back in April of 2007 than what the new 5D Mark II will cost at retail when it hits the market. I bought my 5D for $2800 from Costco, and the new 5D will cost $2,700, but it will have all these incredible new features. Something to think about. I suppose I shouldn’t complain, since I did get about 1 1/2 years about of my 5D before it was rendered outdated by its successor.

So, will I be getting one? Not at the moment, no. My original 5D is still very usable, and I don’t have the deeper pockets of some other folks. I’m still without a good zoom lens. Coincidentally, the same great zoom lens that I like (EF 24-105mm f/4L IS) can be bought as a kit lens with the new 5D, so I definitely encourage you to get it if you don’t have it in your inventory. It will prove its versatility over time, and you will be glad you have it.

At some point in the future, I will be glad to buy the new 5D. Perhaps by that time they’ll have made the video mode more streamlined, and integrated it a little better within the menus and external buttons of the camera, not to mention that I’ll have had a chance to save up for it.

If you’d like to get it though, don’t let me stop you:

How To

Get iMovie '08 to import 3GP files

I recorded a few video clips with my wife’s mobile phone today, and when I tried to import them into iMovie ’08, I found out that I couldn’t. Apparently, I’m not alone, because if you do a search for this on Google you’ll find there are plenty of other people with the same problem.

Fortunately, there are two ways to work this out, but neither is necessarily obvious. Pick one of them:

  • Open up the clips in Quicktime. I was able to open them up and play them right away. Now, export each clip as an MP4 file. You must specifically select File > Export, then select Movie to MPEG-4 from the Export drop-down menu. Don’t just Save the clip, because it’ll package it as a MOV file, which iMovie ’08 will still refuse to import. You must Export it as an MP4 file. You may also be able to export to other formats, but MP4 is what worked for me.
  • Open them clips in Turbo.264, then export them to some format (try Apple TV or iPod Standard, for example). There’s a catch here though. If the resolution of the clips is too small, Turbo.264 may not be able to convert them, and will give you an error. Best stick with Quicktime then.

Now open up iMovie ’08, and go to File > Import Movies, browse for them, and import to your heart’s content. That’s it!

How To

If iMovie '08 crashes…

You can try bothering with the preferences files, or the codecs, or the color profiles, as the forums tell you to do, or you can do the following:

  1. Go to your home folder > Movies > iMovie Events. Locate the folder with the last clips you imported. Delete the iMovie Cache and iMovie Thumbnails folders.
  2. Restart iMovie. For most of you, that’s all you’ll need to do.
  3. If it still crashes, that means one or more of the actual clips themselves weren’t closed properly by the video camera (perhaps you ran out of battery, space on the card, etc.). Open them up in Quicktime (if you have Quicktime Pro) or some other application (like the software that came with the camera) and snip 1-2 seconds off the end of each clip. Save them, then delete the iMovie Cache and iMovie Thumbnails folders (in case iMovie re-created them).
  4. Now restart iMovie. It should work fine now.

A few words to explain some things:

  • If a movie clip doesn’t open at all from the Finder, then it is corrupted. Perhaps only its header is messed up for some reason. At any rate, I have not yet found software that will fix those movie clips. I searched enough, and only found spyware that promises to do it.
  • If a movie clip opens and plays fine in Quicktime, but iMovie crashes when trying to import it, then its ending is corrupted, as explained in step #3 above. Cutting 1-2 seconds off the end of the clip in some software other than iMovie will restore its ending and let you import it without crashes in iMovie.
  • The method I described above has worked reliably for me on three occasions now, and this is after I wasted hours on the phone with Apple Support. It only occurred to them to let me re-import video clips after having me try all of that other stuff, including a re-install of iMovie ’08 and also the creation of a new account to see if the problems re-occur there. Pointless. I say go to the root of the problem and take care of it right away, don’t beat around the bush.

Hope this helps you too.
