How do I change the size of this video file ?

[Edwin01]

Hello,

I'm really new to this, so I ask every one of you guys to be a little patient with me.

I need to change the size of a video, from 608x336 to 720x480. That's because If I leave that video alone and put it on a DVD, then the movie is bigger than my 27" TV and does not appear centered on the screen but more to the right. Attached is an image from GSpot with all the information about that file.

I hope you guys can help me to build an AVISynth script to do that conversion, because I don't understand AVISynth very well



Thanks in advance for all the help

Hi again,

AVISynth can be an option, but if anyone here, knows a better way then I'm all ears (or eyes in this case).

Thanks

this doesnt look like a user guide -- so moving it ..

Hi,

Sorry about that. I forgot to leave the User Guides section before making my post. I didn't noticed it.

Thanks

Did you put the 608x336 video on the DVD or did you do any resize when encoding it? Are you just looking for a way to resize in avisynth or do you want to put the video in center with borders around?
In both cases it can be done, but the borderthing can be hard to calculate correctly, need some tries to make it right some times.

Hi,

Many thanks for taking part of your time to reply my questions, which should look anoying for experienced people like you. Now let me answer your question:

I put it on a DVD+RW and tested it first, before burning it to a DVD+R, to see how it would look. Then I noticed that the image was bigger than my TV screen and more to the right.

According to GSpot, the aspect ratio is bigger (38:21) than my TV wich is 4:3. What I'm looking for, is a way to resize that video from those 603x336 to 720x480 so it can fit my TV screen correctly.

On my computer looks like it was formatted for a wide screen TV. You're also telling me that the video can be centered by using borders ? If it's going to be very difficult, I prefer only to resize until everything looks ok.

But, you're the one who knows how to do it, so I'm open to any Ideas you may have regarding this.

Thanks in advance,

You can just convert it to 720x480 in avisynth and then set your encoder to encode as 16:9 aspect ratio. Its easy enough to set the encoder to 16:9, for ex in CCE you just doubleclick the avisynth file in the encoder list of the main window, click video button and set the Aspect Ratio to DAR 16:9. The simplest avisynth script you could use would look like this for CCE (change last line to ConvertToYV12() for QuEnc):
AviSource("c:\yourfile.avi")
LanczosResize(720,480)
ConvertToYUY2()

Hi again Thor,

Thanks for the help. I'm going to give it a try and see what happens. I'll post my results when it is finished. But not now. I need some sleep, as it is 12:12 a.m. here, and tomorrow, It's going to be a long day for me (too much work at the office, and only one man to do it).

Thanks for all, and take care.

Hi Thor,

Comming back from the work right now. It's been a long day for me and I'm very tired. But here are the news:

Following your indications, I made a test DVD for the said video. Now, I made a mistake and I selected 4:3 on CCE basic. The resulting video, filled the whole screen and appeared centered. However the image appeared a little distorted (that's from my mistake), but even then I'm happy with those results.

I will do it again, selecting 16:9 as you told me, to see what happens. I beleive that this time, the video will appear correctly, well centered and without distortion, but in wide screen format with the corresponding black borders up and down.

Any way, I will let you know about the second test. About my lost hope, for that video, I think I will recover it all.

Again thanks, for your help.

No need to reencode, i often forget to set 16:9 in CCE, i fix it with pulldown exe like this:
pulldown.exe "c:\inputfile.m2v" "c:\outputfile.m2v" -nopulldown -aspect_ratio 16:9

Hi again Thor,


Thanks for your answer, but I made it anyway. I wanted to compare both "versions" to see which one was better, and I like much more the 4:3 "version" over the 16:9 "version".

Wow, if it's not for your help, It could probably never make it.



Now I have one more question, at least for now, that's it: ¿ What's the best font I can use for the subtitles ?

Right now I'm using ARIAL at 20 size. It looks good, and I was planning to keep using it, but if there's another font which looks better on TV screens, then I would like to try it, before burning my video to the final DVD+R discs.

Can you help me into chosing a better font, or can I keep using the same font I'm using right now ?

Thanks in advance,

[thor300]

Font.. I have no idea I guess i would use Comic Sans MS for no special reason, i doubt many others would do that

[Edwin01]

I got the message. Well, I think I will try several fonts until I find a better one or not. 8)

Thanks for all Thor, you've been very helpful. If I have any other doubt, I'll come back, that's for sure, because I've received more help here than at Doom9 site.

Again, many thanks
