Hi John,
I just reviewed this post (10th post in the thread) and re. yours: “Quicktime H.264 not available in Vegas” – this is available. Select Main Concept AVC/AAC (*.mp4) then confirm the custom template settings. Please note: I find that single pass, variable bit rate, maximum 10,000,000 (bps) and average 4,000,000 (bps), provides excellent results from my 1920 mxf source files. This will produce a H.264 Quicktime file which plays back in the Quicktime 7 player. Actually, this is my preferred render format, possibly 2nd best only to Blu-ray which of course you can’t edit.
Hope this is helpful…

John,
Been there, done that. Motion JPEG A and Motion JPEG B, as I understand it, are for interlaced video. My footage is almost exclusively progressive, for which Photo-JPEG is recommended. Not that it makes any difference that I can actually see, having tried them all!
Sure do appreciate your input on this.

John,
I’m only doing the mov renders for uploads to iStock. Their clients can adapt the files any way they want – I’m not involved. Otherwise all the usual options work fine on my machine: wmv, H.264, avi etc.
That said, if I was an iStock client, I would much prefer to receive the original mp4/35 Mps, HQ, EX1 files. The client can download the free clip browser from Sony for the operating system of their choice and convert the original files any way they need them. But iStock is dealing with huge volume and a broad range of source footage so obviously they want to have a common denominator file format – hence mov – for now.

John,
Apparently, when rendering mov files, Photo-JPEG is the codec of choice for progressive video at any resolution. Since none of the 1920×1080 mov codecs will playback solid on my current system, even in a half-size window, I’ll never really know the difference.
The crazy thing is, I took some great advice from Edward Troxel and checked out the MainConcept MPEG-2 Blu-ray codec in Vegas. It plays back like a champ in Windows Media Player in any size window that I can fit on my 1680×1050 screen. You can practically “feel” the difference. It’s so sharp and has such superior contrast range that it’s, by far, the best video render I’ve done yet (except for the green “scan” line at the top of the frame – what’s up with that?). Best of all, the 20 sec. MPEG_HD source (mxf) file is 89Mb, the Blu-ray m2v render is 63 Mb and the mov / Photo-JPEG render is 371.6 Mb!
Of this I’m certain: I don’t need a system upgrade – just patience while we wait for Blu-ray to take over!

John,
The files were exported from the SxS card to the internal hard drive with Sony Clip Browser, using the mxf-for-nle option which, as you said, converts the EX1 mp4 files to mxf format. The mxf files were imported into Vegas and placed on the timeline then rendered as Quicktime 7 (*.mov) @ 1920×1080.
The jittery playback occurs when playing the .mov file in the Quicktime Player (ver. 7.5) – not from the Vegas timeline – which plays the 1920×1080 mxf file perfectly even in Preview (Full) mode. I also have rendered the same mxf files to Main concept H.264 with the same poor result @ 1920×1080 but perfect playback @ 1280×720, also in the Quicktime Player.
I absolutely agree re. mov on the PC however avi (uncompressed) produces file sizes in the gigabytes for a few second of footage. The whole purpose of the mov exercise on my part is to comply with the arcane file format requirements of iStockphoto who insist on mov file formatting for uploads to their site! No wonder it takes weeks for them to process your uploads. A 1920×1080 20 sec clip is approx. 200 Mb!

John,
Thank you for your reply. Here’s what I now know. Something about my system is preventing smooth playback of the 1920×1080 Quicktime .mov because if I import that “jittery” .mov file back to the timeline and render it as a 1280×720 .mov it plays back perfectly from the Quicktime player. I believe this proves that the fault is with the machine or the Quicktime Player and not with the 1920x .mov file.My Vegas 8.0b workstation is:
Dell E6400 Intel Core 2 Duo 2.13GHz, 2 Mb cache, 4Gb DDR2 SDRAM @ 667 MHz
Dual 320Gb eSATA 7200 rpm internal RAID 0 HDD
ATI Radeon Sapphire HD 3870 512 Dual Graphics adapter
Dual Dell E228FP 22″ monitorsIf you can suggest which of these components is/are suspect, please advise.
Thanks again for the help. Much appreciated!
