Hello.
I have transfered a widescreen DV tape to PC, ScenalyzerLive correctly shows it as 16:9, VLC correctly plays it as 16:9 (it's not technically 16:9, but VLC still cannot play REC.601-compliant files properly), however Vegas treats it like 4:3 and I have wasted 2 DVD-Rs in AVS2DVD, because it also thought it is 4:3, the first time it recorded it as 4:3, the second time when I did the override and specified the DVD as 16:9, AVS just pillar-boxed the video and it's still displayed as 4:3, but with black bars on the sides.
And now for the question, how do I fix it, how do I make AVS2DVD treat the input as 16:9, or set the flag on the DVD as anamorphic, without reprocessing the files prior to dropping it into AVS?
Here's the info from AVS:

You shouldn't be wasting disks, test the iso/video_ts folder in VLC before burning.
There is a way to tell A2D the correct A/R as well as other attributes by right clicking on the file in the main window
Edit source title info/video display aspect ratio/ 1.78
You should also check the interlaced/progressive status to make sure that is also recognized properlyLast edited by davexnet; 26th Feb 2023 at 18:38.

Yes, I have now learned that lesson, then again, I had 16:9 sources earlier and ti was working fine.
I tried editing from 1.333 to 1.778, it returned error, perhaps I should have entered 1.78.
However, I have managed to solve the problem, I cecked the option to edit command parameters and there I checked the apect ratio flag from 4:3 to 16:9. I wonder, if it would work, if I entered some other ratio, such as 64:27. -
Works for me.
The way you did it will complete but in some situations, the correct cropping will not be applied to the picture.
This is because a2d crops/adds borders based on the default or this valueLast edited by davexnet; 27th Feb 2023 at 11:47.

It shows for me that the value is invalid, perhaps I should try different decimal separator.
I usually do note require cropping, preservatio of the original recording is usually the desired outcome.
I will definitely experiment with different aspect ratos in the command chain soon. -
Fixing it after the DVD was authored (VIDEO_TS folder) is more inconvenient than doing it right in the first place because you would need to change the flag not only in the IFOs (which is easy) but also inside the VOBs (which is tedious and requires multiple steps).
Although you could get away with just changing the IFOs as they are supposed to have precedence over the VOBs, but it's not guaranteed to play correctly that way in every player. -
There is something that I simply do not get with the OP's .avi (maybe an actual sample of that will throw some light)
But why should a DV, if it is recorded as 16:9 have a DAR of 4:3 ?. So surely that is what a2d is picking up.
On the other hand a2d picks up the FAR correctly. But is that recorded in the header or the '16:9' is not native ?
Something odd appears to be going on with a2d.
I do not have a 16:9 DV to test but I loaded a 4:3 one and got these results:
Compression: Canopus DV
BitRate Mode: CBR
Avg BitRate: 24442 kbps
Min BitRate:
Max BitRate:
Resolution: 720x576
Display AspectRatio: 1.333
Pixel AspectRatio: 1.067
Frame AspectRatio: 1.249
Standard: PAL
So while the 16:9 FAR is reported correctly >> 1024/576 = 1.777... one, atleast I, would expect the 4:3 FAR to be reported as 768/576 = 1.333 whereas the only reason I can find for 1.249 is 720/576. Unless that is an ADVC issue.
Maybe some kind person can upload an independent 16:9 sample straight from a camera and likewise a 4:3 sample -
The problematic file:

Interesting that the FAR in this 'good' sample reverts back to what my 4:3 sample reported.I just wonder if you invoked sclive before it had the opportunity to inspect the 'bad' tape and assumed 4:3. And having started the transfer it realised that the original AR was 16:9 but was unable to change it since the header was already written.What I would also like to see is some of the 'bad' one just to see if there is a way to correct it in a2d other than what you have done.
-
You sure about that ?
Feeding sample.avi into a2d produced a true 16:9 ie 'good' file
VIDEO INFO
Time: 30 seconds
Compression: Sony DV
BitRate Mode: CBR
Avg BitRate: 24442 kbps
Min BitRate:
Max BitRate:
Resolution: 720x576
Display AspectRatio: 1.778
Pixel AspectRatio: 1.422
Frame AspectRatio: 1.25

So if this is the same video as you reported in your OP, we are getting conflicting results in a2d -
So there is your 'fix'.
Cut/resample your 'bad' file - maybe just cut out the first second. The header gets re-written and you end up with a healthy file. -
I think I have identified the problematic section, something happens at the very end, I have no clue as to why.
-
Well we now have a 'bad' sample to work with. a2d still thinks that this is 16:9 although it reports a 0 seconds run time. And it created a 16:9 dvd with no input on my part.
Probably just a glitch in the tape assuming this is a 'one off' -
I dropped this sample into AVS and it shows DAR 4:3. I dropped previous sample with a healthy segment and showed 16:9.
Maybe it's a glitch indeed, at least it can be fixed with command line parameter edit on my part. I will be inspecting the endings of files more closely for such anomalies and if I see 4:3 in AVS that would be a red flag, though I don't use ti that often, as less and less people want tapes to DVD, which is a good thing. -
There is clearly a conflict in information. Here is what my vers. of a2d produces for the second sample
-
OK, it works perfectly fine in 2.3.2. I think this might require the attention of the creators of the software, if it's still being developed and updated.

All old versions are here:

But I may just have been lucky since there are other tools in play as well. -
