352 x 288 for dvd

[Will Hay]

I appreciate I should be capturing (FreeVCR) at 720 x 576 for encoding (TMPGEnc), but what's the result of encoding using a capture at 352 x 288?
I tried a 720 x 576 capture last night using huffyuv and despite my relatively decent system was losing 25% of frames.
I must admit I haven't tried the PicVideo codec at 720 x 576 but can't see how the codec would make any difference.
Thanks,
Will

When you get your Athlon it should help.

You can try 1/2 D1 DVD resolution 352x480 NTSC (352x576 PAL) - make sure your audio is 48khz for DVD.

I hope so.
I just burnt a one minute clip of the footie (soccer if you're in the US!) using mpeg2 720 x 576 (7.20mb/sec) to svcd and it was horrendous, truly the worst I've ever produced.
I must admit it was captured in 'real time' though using the ATI Radeon, I didn't capture to avi and convert using TMPGEnc - perhaps I'll try that next.
Makes me a little concerned regarding the dvd-r drive I'm due Monday. If I can't create a decent quality what's the point of anything other than vcd?

Until last summer when I upgraded to an Athlon 1800+, I was capturing fine using a Duron 750, 512 pc133 sdram and Windows 2000 Sp2.

What software are you using to capture ?

The faster chip did speed up my avi->mpegII times alot. Almost 4 times faster !

The crap quality was as a result of my capturing directly to mpeg2, not to avi then converting. I thought I'd give it a shot but for £25 wasn't expecting great results.
I'm capturing with FreeVCR but of late Virtualdub - I tried a five minute clip last night at 480 x 576 using PicVideo and lost only 7 frames (of 7500 - 5mins @ 25f/sec), I can live with that!

You aren't the only one who is unable to capture any larger using Huffyuv. I am puzzled despite that fact my computer is Pentium 4, 2.0 GHz processor.

I can only do a small size 352x288 and capturing in Huffyuv is tough. I tried to capture for PAL TV on size 704x576 and this failed. I tried everything, no improvement.

I do believe this may have something to do with my capture card, "LeadTek WinFast A250 MyVIVO". I don’t really know why I am unable to do any greater capture.

My default capture program is WinFast PVR and having no problem capturing 640x480. WinFast PVR does have automatic de-interlacing available.

I also have no problem capturing DivX and Microsoft’s MPEG4 using VirtualDub on the same size of 640x480. However interlacing is a problem when using VirtualDub. I am trying to find the best solution for this problem. I’ve tried “Smart Deinterlacer” and can anyone suggest a better filter?

I still can't capture any larger on any codec. Anyway, I’ll find a way.

I've only tried 720 x 576 using Huffyuv with a Duron 800, and didn't expect miracles
I'll test tonight using different format sizes and then same again after installing my Athlon XP2000 and report back.
The main reason I haven't bothered too much with huffyuv is I can't see any massive increase in quality over PicVideo. I'm sure I'm wrong and whilst have the storage space would be interested to learn from anyone their opions on PicVideo mpeg vs huffyuv quality comparisons.
I have a dedicated video drive set up (2 x 80gb Maxtor D740x's on a RAID 0 - before this I was capturing to my one and only HDD which was laughable.
What's your system spec?

I have been testing different sizes to capture using huffyuv and now able to capture at 640x480. I have to check a little more on the sound as it seems to be a slightly out of sync with the video.

So, now I can only do 352x288 and 640x480. The TV is PAL.

VirtualDub tells me that there is a restriction, "depth 24". I presume size restrictions. Is this correct?

I noticed my video card and its default capture program have something to do with the restrictive capture resolution sizes. All other video codecs I use can capture the same size at 640x480 successfully.

Hacked versions of DivX, the 5.02 version of DivX and Microsoft's MPEG all are at this size without a problem. Size 480x576, 704x576 and 720x576 are problems in my system.

I am unable to do any more and I have to research on it more later.

I now go on to try out the NTSC videos to capture shortly. I hope huffyuv will be better using the American TV, NTSC.

Mine too!
I've just fitted the XP2000+ (from a Duron 800) and the increase in encoding time is incredible!

I just finished re-testing the huffyuv on a resolution size of 640x480 and the sound is out of sync by few seconds with the video.

I now will have to video process the using VirtualDub to fix the sound and this is the only thing I could do. The video file is too big anyway and will get bigger still after the correction. See what happens.

Now I've just finished the video process to correct the sound - much better and no change in size. WOW, the video size is a huge 5.86 GB for a 12.25 minute clip.

I don't think I'll be using huffyuv very much due its size.

I'll try out a bigger resolution later with the sound correction.

The bigger size of 720x576 is way too big with too much interlacing.

The good news is I've fixed the sound for my PAL TV on 640x480 and the way to do it is accuracy of video with sound on 24.964fps.

I got to know that 25fps is no good for huffyuv with the video and sound out of sync. The interlacing as not too bad on 640x480 and this can be corrected with VirtualDub's de-interlacing process.

I now go on to try out the NTSC videos to capture shortly. I hope huffyuv will be better using the American TV, NTSC.

So, now I can only do 352x288 and 640x480. The TV is PAL.

Did you burn this to a dvd-r?
How did it look?
Thanks,
Will

Not yet, I was experimenting it using huffyuv. I haven't got the DVD-R yet. The CD-writer is too old and I am getting the DVD burner sometime this year.
