Canon 5D, 7D, T2i MP4 file issues

MUTTLEY wrote on 3/3/2010, 9:22 AM

Finally trying out the whole DSLR thing and picked up a T2i. When it first got here got a couple clips and dragged em right to the timeline which got me excited but they were just a couple short little ones in my front room, nothing worth editing or rendering. Went out yesterday to do some test shooting and started having issues with the files as soon as I started trying to play with them in Vegas.

This is in a 1080 24p project. Windows Vista 64, Sony Vegas 32 Bit Version 9.0c (Build 896). Intel Dual Core Extreme and 8 gigs of ram.

I have about 45 clips of varying length. Most 1080p, a few 720p. If I select them all in the explorer tab and try to drag them to the timeline Vegas crashes. If I try to drag them in through Windows explorer Vegas crashes. By picking and choosing one at a time I was eventually able to get enough footage on the timeline to try cutting a little something together. Playback was choppy even in draft mode with fx off, very hard to cut to music as it would show the cut in the preview window after the actual cut. Also kept getting a lot of red frames. Would close and re-open Vegas with mixed success in getting rid of them. As suggested elsewhere tinkered with the Dynamic Ram Preview settings and some of the internal memory settings, tried changing the Thumbnails to only show head and tail. None of which seemed to have any effect on either the red frames of playback.

Eventually kind of Frankenstein edited together about 2:30 mins, not saying they're any good but it's something. Now render is proving impossible. Either I get the infamous "System Low on Memory" error even after rebooting with nothing else running or get a full on crash (details below).

So, I'm hoping my newbieness with the Canon files are the culprit and someone knows a magic cure. Anyone out there thats used the 5d or 7d have any of this? Workarounds? Suggestions? Was really excited about my new lil mini cam and this is currently a buzz kill! I'd like to do some more testing and get some footage online but not worth the effort till I sort this all out.

I wholly disagree. For numerous reasons. The Scarlet offers something NONE of these cameras do. And that is the ability to stretch beyond 1080p and with a REAL codec. And beyond that, to do so with cinema lenses. For those in the upper end of the market, the 5D/7D will become a distant memory. No moire, no chromatic aberration, no 700 lines of resolution (about 1200 instead), no codec breakup, ability to use the lenses all the other on-set cameras use, etc.

At the consumer end, the Scarlet's thunder has been stolen. No doubt. But I've said it from the day the Scarlet was announced. The only Scarlet that will matter is the one with interchangeable lenses. The fixed lens model at the lower end of the market will have appeal to very few people.

But if I could trade my EX1 on an S35 Scarlet, I'd do it in a heartbeat.

All good points. But a great camera is more than a spec sheet.

Quite true. However, if the images look as good as I saw from the beta cam, Canon won't be able to touch it. And I've shot the Canon, and am pending an order on the 7D...

I agree. And DSLR's are certainly very limited in functioning as a video camera. Either way, I can't imagine how cool the products will be in a couple of years from now.

@MUTTLEY: Perrone I'm not sure that the reason you gave is either

Perrone is correct. FAT32 is the file system on all these cards, and FAT32 has a maximum file size limit of 4G. There may be other reasons for having other limits on the camera, both heating and tax issues. The reason Canon stops at 4G is because they have to stop at 4G however. You can not store more than 4G in a single file on FAT32, and all these cards are formattet FAT32.

Now, we could as Canon to implement other file systems on their cards, but I am not sure how useful that is...

Perrone is correct. " and so is Terje. Fat32 licensing is cheap compare to NTFS, plus Fat32 is the most universal format for most devices. If I remember correctly, Fat32 drivers are fairly compact compared to portable NTFS drivers. But the key to these issues besides cost of licensing is the speed of camera's hardware and firmware writing to the chip plus how much heat and battery power are consumed doing it. A simple 5 to 10% increase in heat and power consumption can be critical.

concept wise, the Canon could do 2K+ easily, but the codec and power/heat management are issues that probably are the show stoppers for now. Canon has been doing some great things recently, so maybe it's in the near future.

Sorry, didnt mean fat32 was not a part of the reason for the limitation, obviously fat32 has a 4 gig limit but what I was trying to say was that it doesn't appear to be the only reason for it. From what I understand the SDXC cards will be exFAT and not have that particular limitation but the X2i will still be limited to 4 gig recording times which would imply to me that there are other motives for it.
