custom profile help needed

I've been trying to create a custom profile, starting with MPEG4, hoping to find settings which will allow me to upload good quality HD video to YouTube in less than 4-5 hours' time for a 10-15 minute video. I'd like something better than MEPG2, but I think (only for the purposes of YouTube) I can live with slightly less quality than full MPEG4. For my own use I'll continue to burn and/or playfull H.264 AVC. The profile I've started with seems to look okay on the screen, but it appears that it isn't applied to videos when I click to use the new custom profile. At least,when I think I've applied the custom profile, there is no change in file size from produced version done in the 1920X1280 profile.

Here's the profile, with the changed values in italics: Resolution of the "custom profile" is 720X1280 - bitrate 13,000,000 - audio bitrate 128 - quality indicator 6 (looks like that can't be changed unless it's moved to 1) - Framerate remains at 59.94 - "profile type"="main profile" - avg bitrate 13000000.

I have 5 screen shotsof the profile settings and I can post them, if they will be helpful.

In summary, I haven't changed much, so far except the resolution and the audio bitrate. I would be grateful for advice on whether (and how much) to change the average bitrate, file type, video bitrate of 13,000,000, and whether the quality indicator can or should be changed.

I'd also be grateful for advice on how to be sure the custom profile is going to be applied. If I click on SVRT while in the MPEG4 mode, the resulting dropdown box does not contail the "custom profile" and the "Apply" button is blacked out (inoperative).

Hi Bill,
make sure you give the frame sizes correctly - threw me out for a second
1280 x 720 = HDlite
1920 x 1080 = Full HD

I have the quality indicator set to full on the right. I have checked deblocking.

1. Please attach a sample of the video you're editing, 5 seconds of footage would be great. state source, Camera make and model please.
2. I know we've gone through the SVRT custom use previously and i want to make sure what you're using is SVRT/mp4 compliant.

Dafydd - Thanks for your reply. I did write to the forum recently, about attempting a custom profile, but I had other things about PD to learn, so I never quite got to the custom profile.

You wrote:

Would it help if I also post the screen shots of my recent attempt to create a custom profile with PD 10? I'd post them as attachments to an email to this thread.

I will also post a short clip of the video in question, once I know whether you'd also like me to post the screen shots. I assume you want a clip of the video itself. That video has previously been rendered in H.264 (so if I post a clip of the video itself, it would be in AVC), but I could post one of the original, unedited MTS clips if that would be preferable.

FYI - the video was shot at AVCHD 1080, 60p using a Panasonic TM900 camcorder.

More info on this - I just checked the Produce file of that video, after it rendered in (what I hope was) my attempted custom profile. The file size is 1.13 GB, while the file size of the original H.264AVC file (no clips were changed or edited, except for the decrease in resolution to 720X1280 and the decrease in audio bitrate from 360 to 12 - so maybe my custom profile was applied after all. The resulting file play very well on my 24 inch computer monitor (yes, my camera work and my control of exposure, contrast, WB and noise need a lot of work - but that will come, in time).

That new audio bitrate is 128, of course. I keep forgetting that this forum uses smilies by default. Bill Hansen

Hi Bill,

I think you're finding the info out yourself and don't need my further input.

I'll keep reading the thread and jump in if I need to.

Dafydd

Thanks Dafydd. I'll hold off on posting the screen shots and the video clip. My next "try" will be reducing the video bitrate from 13Mpbs to 9 Mpbs, same 720X1280 resolution. If that works, it may give me the compromise I've been looking for.

And once again - many thanks to you and all the others who are willing to offer your help. You make PD possible for those of us who are newcomers. Not every program or forum is lucky enough to have people like you.

Bill
