How to Edit Videos in VirtualDub Easily?

VirtualDub is the open-source and portable video editor with the ability to compress videos while preserving good quality. Although it's not so fully-featured as other professional video editors, it certainly can accomplish more than a few tasks that you might think you need other separate applications for. Here let's see how to edit video using VirtualDub.

Now let’s take a look at video editing in VirtualDub.

Steps to Edit Videos in VirtualDub

1. Split & Trim Video with VirtualDub

VirtualDub has the ability to split videos or trim a portion of a video file with the position slider. To do this:

1. Go to the Video Menu and check the "Direct stream copy" option. Then go to the Audio Menu and do the same.

2. Use the "Edit" > "Set selection start" and "Edit" > "Set selection end" commands to select a portion of video. This can also be done through the mark-in and mark-out buttons below the position slider or through the Home and End keys on the keyboard. Then the currently selected part will now turn blue at the slider.

3. After that, click the "File" > "Save as AVI" menu command to save the AVI segment.

2. Join & Merge Video with VirtualDub

To join/merge multiple video files:

1. Go to "File" > "Append Avi Segment" to add another AVI video you want to have in your big video. You can only add one file at a time, so if you have many small video parts, you have to repeat this step and that may cost a lot of time.

2. Go to Video menu and make sure "Full processing mode " is selected there.

3. Click "Compression" under the Video Menu and choose the video codecs for your output videos. After that, go to "File" > "Save Segmented AVI" to save your work to your computer.

3. Crop Video with VirtualDub

VirtualDub allows you to crop at the beginning of any video filter, you can do it by following the steps below:

1. Check that you're in "Full Processing mode" and then go to "Video" > "Filters". You’ll notice that there’s a Cropping button that’s not quite clickable (because it’s only enabled after you have chosen a filter).

2. Then click on Add... and choose "null transform". That doesn't do anything to your video, but will ungray the Cropping button now.

3. In the Filter input cropping dialog box, you can either drag sides or adjust the offsets to crop videos.

Tips: Change the dimensions will reduce the video quality, but you can use the resize filter to make the cropped video as the original video's resolution.

4. Rotate Video with VirtualDub

VirtualDub also enables you to rotate video in different angles. Here's a little trick to rotate your videos with it.

1. Choose the Video Menu and go to "Filters".

2. Then click on Add..., choose "rotate" and click "OK". Then the Rotate filter will provide you will all the necessary options to rotate your videos.

You will certainly notice the presence of the "rotate 2" filter. Indeed, it allows you to can choose the degree of rotation of the video.

5. Compress Video with VirtualDub

VirtualDub is an ideal program to compress a video file while still retaining the quality of the original. Follow the steps below to see how it works.

2. As shown in the image, select the XVID MPEG-4 codec and click Configure button to make Xvid settings. You can lower the "Target bitrate" to make your video smaller.

3. Then go to the Audio Menu and select "Full processing mode", and click "Compression" to open the dialog, where MPEG Layer-3 is recommended.

4. Now, to create the compressed file, choose the "File" > "Save as AVI" option and give a new name for the compressed file. Virtualdub should now start saving the compressed file to your chosen location.

3. Go to the Video menu, select "Direct stream copy" and then go to "File" > "Save as AVI" to save the new audio.

1. First download VobSub filter and then unzip to install it. During the VobSub installation, please make sure that you've selected both "VobSub for VirtualDub" and "TextSub for VirtualDub and AviSynth" under plugins. You'll also need to specify the directory where you've unzipped VirtualDub.

2. Then go to "Video" > "Filters" to bring up the Filters dialog. Choose TextSub, click OK to browse to your subtitle file. When You’re ready, press OK.

Create videos with 5.1 audio for the Apple TV

The new Apple TV eats near-Blu-ray quality X.264 video for breakfast—but when it comes to audio, the device is a picky one. With AirPlay streaming, on the other hand, audio is much more flexible than video. What's going on inside the diminutive media player, and what should those of us doing our own audio/video encoding keep in mind?

Audio inconsistencies

The Apple TV will play audio encoded as MP3, AAC, Apple Lossless, and several other formats. The audio that accompanies X.264 video, on the other hand, can only be AAC or AC3 (Dolby Digital, often 5.1 channels surround). But the Apple TV doesn't actually know how to decode the latter—if you want to play multichannel audio through your Apple TV, you need to hook it up to a TV or an amplifier that can accept audio in AC3 format and decode it. Most of the time, this isn't an issue, because AC3 is also used in HDTV broadcasts, so most high definition TVs can decode it, as can specialized "surround receivers" with many, many speakers that decode multi-channel digital audio for a living.

However, if you hook up your Apple TV to a TV or other device that expects to receive uncompressed PCM audio, the Apple TV's unwillingness to decode AC3 can be a problem. In this case, if you attempt to play a video with just an AC3 audio track, the Apple TV will display an error message and refuse to play the video file. Apple itself shrewdly avoids this problem by always having a stereo AAC audio track in all the videos that it sells, so the Apple TV can simply fall back to the stereo track if the display device it's hooked up to can't handle AC3 audio. And the iPhone, iPod touch, and iPad can't decode AC3 audio either, so they depend on the stereo track as well.

Creating your own

So what does this mean when creating your own videos?

Most of the time, it shouldn't matter, as most audio sources are stereo or even mono, so a stereo AAC track is all that's needed. But when ripping DVDs to an Apple TV friendly format, you may want to preserve the original 5.1 audio track as well as create a stereo AAC track, just like Apple does. Pavtube BDMagic for Mac, the powerful video conversion tool, will do this without much trouble.

As a versatile DVD Ripper, the program can stream not only DVD to Apple TV 4/3/2/1, but also rip DVD to iPad (iPad Pro, iPad Air 3, ipad mini 4), iPhone (iPhone 7, iPhone 6S Plus, etc.) and many other popular video/audio format like WMV, AVI, FLV, 3GP, MKV, AIFF, AAC, and more. Play DVD on Android mobile phones is also a simple case with this DVD converting tool.

If you're running a Windows PC, simply turn to Pavtube BDMagic, which allows you to rip DVD to Apple TV format in Windows (Windows 8/8.1/10).

How to Rip DVD to Apple TV with 5.1 Audio?

Step 1: Run Pavtube DVD Ripper for Apple TV, and import DVD movies files to the program. You can directly load DVD source from your DVD disc by inserting it to your DVD Rom, or you can import source movies from ISO/IFO file or a DVD folder stored on your HDD. 

DVD to Apple TV Converter

Pavtube DVD to ATV Converter checks the main title of the DVD automatically once you loaded the source movie. If you don’t want to rip the main title, you can uncheck it, and tick off whatever title you want to convert for Apple TV. Plus, you can select your wanted subtitles track to be embedded into the resulted files before conversion.

Step 2: Choose “Apple TV 3 Dolby Digital Pass-through (*.m4v)” as output format 

In order to have Dolby Digital 5.1 surround sound in the final output files for Apple TV 3, you should select “Apple TV 3 Dolby Digital Pass-through (*.m4v)” as target format.

The best video format and settings for Apple TV 3/4 DVD streaming:

Format: Apple TV 3/4 Dolby Digital Pass-through (*.m4v)

Video Settings

Audio Settings

Codec: h264 
Resolution: 1920*1080  
Bit Rate: 6,000 kbps 
Frame Rate: 30 fps

Codec: aac  
Sample Rate: 48,000hz
Bit Rate:160,000 bps  
Channels: Stereo

By choosing this format, you will get two sound tracks in the resulted 1080p m4v video, one is stereo, and the other is AC3 encoded Dolby Digital 5.1 pass-through. When your Apple TV is connected to audio receiver, the 5.1 surround sound will work. When ATV is connected to your HDTV only, the stereo track will work.

Step 3: Rip DVD for Apple TV

Click Convert button to start DVD to Apple TV conversion. When the DVD to 1080p M4V conversion task is finished, you can click Open button to get the converted DVD files that are available for Apple TV Dolby Digital 5.1 pass-through.
