File size limitation for HD

I'm pretty sure it's been discussed before and the file size limit was increased to 500,000 but for full 1920x1080i that many times is only 15 seconds. It ias not unusual for an .avi for 25 seconds to be 650,000 to even 800,000 size. I feel that shortening many of the clips to less than 15 seconds really cuts the meat out of it. With standard quality 500,000 is plenty, in fact excessive. If we will eventially have our 1920x1080i clips reduced automatically to other quality and sizes I think we needd at least 650,000 to be competitive with the SD clips. Whatcha think?

Hi Phantomewo,

For HDV shots, we are now accepting clips in the native HDV format. This will make the clips MUCH smaller in file size, and of a higher quality than transcoded clips.

If you are coming from another HD format, you will need to go with Photo or MotionJPEG (depending on interlacing). These codecs will produce bigger files, but please try not to go over the 500MB limit - remember, you can always cut the clip into multiple shots.

The average duration of a video edit these days is typically under 5 seconds, so you should be able to create a clip with enough "tail" on either end to make it perfectly usable by editors.

Of course, if you have a REALLY good reason for going with a longer, continuous shot, we'll probably make an exception (depending on what the curator had for breakfast) ;-)

Hi,

Just tried to upload a native hdv clip (m2t)
and it is showing as "unable to process clip"

"Am I misunderstanding the post above" ?

WOW, ok I just converted 95 clips into .AVI with QT codex for UL. I screwed up by not keeping the original m2t files. As Kenny1 has said, for clarification, m2t files are acceptable?
.
Thanks for all you quick responses.

All files should be prepared as Quicktime .MOVs - NOT avi's or m2t's.

Please review our https://www.pond5.com/index.php?page=document_view&document_name=video_requirements. As we've always done, we only accept files prepared using the Quicktime file format. What's new is the fact that we are now accepting the native HDV (mpeg2 transport stream) codec. But they should still be .MOVs.

If you run into difficulties or have questions, you can drop us a line at tech@pond5.com (and include info about your camera, editing program, and current workflow) and we'll do our best to assist.

thanks, will do it ;)

If you accept the the HDV Format, can I encode to it instead of the photo-Jpeg? I am coming from the DVCPro HD codec originally. Gong to HDV instead of P-Jpeg is a huge savings on file size, but since I that codec is not native to the original capture, i wasn't sure about the conversion.

Also can there be a trade off between file size and clip duration. In other words if it is under 500MB can you exceed the 30 sec duration without there being an issue, or must both criteria be met every time (maybe this is a cll the curator can make upon review)?

No, please do not convert non-HDV native clips to HDV -- there are severe compression and quality issues the result. Stick with PhotoJPEG for DVCPRO HD material.

In terms of the file size and duration limits, these are "soft limits" -- if you've got a good reason to go over, we'll generally accept them regardless.

Should these be encoded as 960x720 with a .75 pixel aspect to make it anamorphic? or should I encode them at 1280x720 using square pixels? Just wasn't sure how you handled the transcode.
