Video Rendering Size Problem

[KamalYS]

Hello,

I am using VS10 and before rendering it is showing 63GB of space is required. I am trying to copy DVD folder on hard drive.

On the Share screen at the bottom is shows: 31.94(34.29) GB/9 Hour 54 Min 10 Sec

While on the final screen of burning it is showing:
63.44 GB / 8.57 GB

Now, please tell me how can I render and burn the Video on Hard Drive, large enough to accommodate in a 4.7GB DVD?

In this video I have inserted 15 videos in WMV format and the combined size of all video is 1.43 GB. Don't know why the size has increased to such an extent!

Because WMV is a highly compressed format, it takes up very much smaller space. If you are wanting to burn a standard definition, single layer DVD, the video has to be in mpeg-2 format, which is far less compressed. In other words, the 1.47 GB of WMV video will be greatly expanded in the conversion to mpeg-2.

On top of that, WMV is not an easy format to edit, and the conversion to mpeg-2 in Video Studio can be both complex and very time consuming. If at all possible, it is better to either avoid WMV or else first convert your WMV to mpeg-2, and then do your editing...

Hi,

Thank you very much for your reply, I will try mpeg-2 or avi formats, is there any other way to put more data on a single layer DVD? thanks.

Lower bitrates = more data, less quality

Higher bitrates = less data, better quality

You'll have to determine which is more important to you, the amount of data or the quality, to find the bitrate that works the best for you.

It really depends what you want to do with the DVD's.

For example, you could output your project to DivX, which is highly compressed, and you can find quite a few DivX capable set top or standalone DVD players that will enable you to play your stuff. You won't be able to use any DVD menus, however.

A common usage for DVD converted to DivX would be for people wishing to back up several movies onto one single layer DVD disc - quite handy for trips where you might view the movie on a laptop and the slight loss of picture quality isn't so important.

Your main problem is that you are dealing with wmv source material. Whilst you can play wmv clips on a pc, there's not too much else you can do with them, and any transcoding from wmv to another format, e.g mpeg2 or divX, will necessarily result in some loss of picture quality. The transcoding will also take a lot of time, depending on the speed of your pc.

If you choose to output to mpeg2, you can make a regular DVD, with menus. You would be able to use a video bitrate of 4000 to 6000 kbps, and using compressed audio, you could have a project duration of from 95 to 140 minutes.

I would do some tests, encoding short wmv clips to mpeg2 at various video bitrates in order to establish a suitable bitrate, balancing the resulting file size and picture quality.

Hi,

Thank you very much for your kind assistance. I live in PAL country and therefore now I am converting the WMV video to AVI format, with following settings, please let me know if you think these settings are most appropriate, but if you think these are not, please do suggest your configuration:

VIDEO:
Output format: AVI
Codec: MS-Ppeg4-V2
Aspect: 4:3
Fps: 25
Bitrate: 1152

AUDIO:
Codec: MP3
Frequency: 44100
Channel: Stereo
Bitrate: 128


Thanks!!!

I would certainly NOT use that MS-mpeg4-V2 format. You are just exchanging one problematic format for another from a video editing point of view. I assume you have a Microsoft codec pack installed, but mpeg-4, even using the .avi extension, remains highly compressed and difficult to edit. And it is still not the mpeg-2 format required by video DVDs. Moreover, Video Studio sometimes has difficulty with mp3 audio, though I cannot comment specifically on mp3 produced by a Microsoft codec.

9 Hour 54 Min 10 Sec... to accommodate in a 4.7GB DVD?

10 hours is way too much for a single-layer DVD. I try to keep my DVDs to 90 minutes if possible. With your low-bitrate (low-quality) WMV files, you don't need "DVD quality" and I would guess you can squeeze 3 hours onto a DVD.

As Ken said, standard video DVDs are MPEG-2 with LPCM or AC3 audio. And, since you live in a PAL country, MPEG-2 audio is also an option because PAL DVD players are also required to play MPEG-2 audio.

You should be able to go directly from WMV to MPEG-2. If you have trouble with that, we can give you some suggestions. But as Ken also said, MPEG-4 is not the solution.

Here is a handy online Bitrate Calculator. You enter the playing time and audio format(s), and it tells you what bitrate to use for the DVD.

Or, you can estimate file size with the following formula:
File Size in MB = (Bitrate in kbps x Playing Time in minutes) / 140

The formula works for any audio/video format. Use the combined audio & video bitrates, and if your format uses variable bitrate, you must use the average bitrate.

FYI - WMA is more efficient than MPEG-2, so this a little like comparing "apples to oranges", but your WMA files (at about 10 hours and 1.5 GB) have a bitrate of around 350kbps. A typical commercial DVD has a bitrate in the ballpark of 5000kbps.

Ken Berry, 2Dogs, DVDDoug,

Thanks a lot for your valuable inputs, I will now, once again, convert my WMV videos to Mpeg2 format and the suggested audio settings.

I am right now using Free Video Converter by KoyoteSoft, is there any better and efficient video converter?

Thanks.

VideoStudio
Just place your wmv on the timeline and go to the [Share Tab]
Select [Create Video] and choose an appropriate output format.

Hello sjj1805 and others, commercial version of these videos even has 6 30 minutes episodes with extremely fine quality, but making video with VS10 is not allowing me to burn more than 3 on a single layer 4.7 GB DVD. Can you please tell me how can I burn 5-6 episodes on a single DVD?

Also, our of the total 17 episodes that I downloaded, some are in WMV format and others are in FLV format, I am using a video converter to convert FLV videos to WMV or MPEG format, is it right way to do? what should be the optimum setting to have more videos on single DVD without compromising too much on the quality?

thanks.

The reason the manufacturers of these discs can fit so much info on one disc is that they start with a far higher quality video than you can ever hope for, and then use an encoder that makes perhaps 20 or more passes and costs hundreds of thousands of pounds, so you can either copy them and spend a fortune or do as you have found out and put fewer episodes on each disc.

And, most commercial DVDs are dual-layer. (I don't know about your particular DVD.)

This is a very hard question to answer... I think you'll have to experiment, and judge for yourself. It depends on the quality of your original video, and how picky you are. People who are used to watching Blu-Ray movies, are probably more picky than me!

Like I said, if you start out with high-quality video, you can fit 90 minutes of "DVD quality" video onto a single-layer DVD (~6000kbps video + Dolby audio). When I've "pushed it" beyond 2 hours, I've started to notice the quality loss (on my standard definition TV).

I'm not trying to tell you what to do, but personally, I wouldn't be so concerned with squeezing the maximum number of episodes on one DVD. I wouldn't want to change discs in the middle of a movie. But otherwise, I wouldn't mind getting up to change discs every 90 minutes or so, at the end of a program/episode. In might even be more convenient to have multiple discs. If you've got several episodes on one disc and you stop watching in the middle, you might not know where you left-off... You probably remember the topic, but you might not know the chapter/episode number that you last watched.
