Convert DVDs to DivX with USAsoft: Best Settings and TipsConverting DVDs to DivX can save storage space and make your video library easier to play on a wide range of devices. USAsoft DVD Video DivX Converter is a tool designed specifically for this purpose, offering a balance of speed, simplicity, and output quality. This article walks through the conversion workflow, recommended settings, tips for preserving quality, and troubleshooting common problems.
Why convert DVDs to DivX?
- Smaller file sizes: DivX uses efficient MPEG-4 based compression for much smaller files than uncompressed or DVD-structured formats.
- Compatibility: DivX is supported by many standalone DVD players, older media players, and portable devices.
- Convenience: Single-file movies are easier to manage, stream, and back up than full DVD folders or ISO images.
Before you start: legal and practical considerations
- Make sure you own the DVDs and have the right to make backup copies in your jurisdiction. Circumventing copy protection on commercial DVDs may be illegal in some countries.
- Check the DVD for region coding and copy protection; many commercial discs include encryptions that require additional tools to read. USAsoft may not handle all copy protections natively.
Installation and initial setup
- Download and install USAsoft DVD Video DivX Converter from the official source.
- Install any optional codecs or plugin components the installer recommends; DivX or other MPEG-4 codec packs may improve compatibility and quality.
- Update the software if prompted—newer builds often fix bugs and add format presets.
Workflow overview
- Rip the DVD (read the disc and extract VOB/MPEG-2 files).
- Load the ripped files into USAsoft’s converter.
- Choose a DivX profile or custom settings.
- Adjust audio/subtitle/chapter options.
- Encode to DivX and verify output.
Some users prefer to rip with a dedicated rippage tool (e.g., MakeMKV, HandBrake, or similar) and then use USAsoft for the conversion step. This can bypass copy protection or give more control over source selection.
Choosing the right source files
- For best results, use the main movie VOB files or an uncompressed MPEG-2 rip as the input rather than a heavily processed or low-quality MPEG file.
- If the DVD contains multiple angles or extras, pick only the main title to avoid unnecessary conversion time.
- When possible, work from a lossless or minimally altered rip to preserve maximum quality through compression.
Best DivX settings (recommended)
- Container/Format: DivX AVI (or MP4 if DivX MP4 profiles are supported).
- Video codec: DivX (MPEG-4 ASP).
- Resolution: Keep the original DVD resolution (usually 720×480 for NTSC or 720×576 for PAL) if you want to preserve detail. Downscale to 640×480 or 560×416 only if you need smaller files.
- Frame rate: Match the DVD source (29.97 fps for NTSC, 25 fps for PAL).
- Bitrate mode: Use two-pass VBR (variable bitrate) for the best balance of quality and size. If two-pass is too slow, single-pass VBR is acceptable.
- Target bitrate: For good quality at modest size, aim for 900–1500 kbps for standard-definition movies; increase to 1800–2500 kbps if the movie is visually complex and you want fewer artifacts.
- Keyframe interval: Set to 2–4 seconds (i.e., every 60–120 frames for NTSC) to help seeking performance.
- Audio codec: MP3 (LAME) or AAC if MP4 output is used. Bitrate 128–192 kbps for stereo; 192–256 kbps if you want higher fidelity.
- Channels/sample rate: Stereo, 48 kHz (or 44.1 kHz if preferred).
Subtitle and audio handling
- Soft subtitles: If you want selectable subtitles on supported players, keep them as a separate subtitle track (e.g., SRT) if USAsoft supports it.
- Hard subtitles: If the target device doesn’t support soft subtitles, burn (hardcode) the subtitles into the video during conversion. This is irreversible.
- Multiple audio tracks: Choose the primary language track; you can include additional audio tracks if the converter supports multi-track output (rare for DivX/AVI). For most cases, export a single audio track.
Preprocessing tips to improve quality
- Deinterlace interlaced DVD sources before encoding. Interlaced content converted as progressive can look jagged. Use the converter’s deinterlace option or preprocess in a tool like HandBrake.
- Denoise modestly for older or noisy DVDs—overaggressive denoising blurs detail.
- Crop black borders to remove letterboxing if you want smaller file size; ensure you keep the movie’s aspect ratio.
- Use sharpening sparingly after denoise to restore perceived detail.
Speed vs. quality tradeoffs
- Two-pass VBR and higher bitrates increase quality but take longer.
- Hardware acceleration (if USAsoft supports it) speeds up encoding but may reduce compression efficiency or introduce artifacts. Test short clips to compare speed and output quality.
- If you need many conversions, create a test clip (1–3 minutes) to iterate on settings before batch processing full movies.
Batch conversion and automation
- Use USAsoft’s batch mode (if available) to queue multiple DVDs or movie files.
- Standardize settings (resolution, bitrate, audio) for efficiency.
- Label output files clearly with title, year, resolution, and bitrate—for example: Movie.Title.(2003).720×480.1500kbps.avi.
Checking output quality
- Watch samples from beginning, middle, and end to spot bitrate-related issues (mosquito noise, blocking) and audio sync problems.
- Compare file size vs. perceived quality; if quality is poor at chosen bitrate, increase by 200–500 kbps and re-encode a short clip to test.
Troubleshooting common issues
- Playback problems on devices: Try using MP4 container, lower profile level, or different audio codec. Some older players have strict codec/container support.
- Audio desync: Re-rip the source ensuring correct frame rate; try remuxing audio separately and recombining.
- Copy protection errors: Use a dedicated ripping tool that can handle protections, then import the decrypted files into USAsoft.
- Crashes or freezes: Update to the latest version, ensure required codecs are installed, and try converting a small clip to isolate the issue.
Alternatives and when to use them
- If you need more advanced control, open-source tools like HandBrake or ffmpeg offer finer-grained options and broader format support.
- For simple, fast conversions with presets for many devices, commercial tools with modern codec support (H.264/H.265) may be preferable to DivX today.
Example settings summary
- Container: DivX AVI
